Utilization of a cooperative multiagent system in the context of cognitive radio networks

Abstract

In this paper we propose an approach to solve the spectrum allocation/sharing problem using Multiagent System (MAS) cooperation that enables Cognitive Radio (CR) devices to share the unutilized spectrum dynamically and opportunistically. We introduce briefly the problem of static spectrum assignment and propose an approach to solve this issue. The key aspect of our design is the deployment of agents on each of the CR and Primary User (PU) devices that cooperate in order to have a better use of the spectrum. An example scenario is also presented along with our proposed model. © 2009 Springer-Verlag.
